Charging the sensors
The QE2008-W sensors have an internal lithium-ion polymer rechargable battery, which assures a long operating
time of the device. Compared with traditional battery technology, lithium-ion polymer batteries are lighter, charge
faster, last longer, and have a higher power density for more battery life.
To charge the QE2008-W sensor, do any of the following:
• Connect the sensor to a power outlet using the
charging USB-C cable and the USB power adapter.
• Put the sensor in the QE2008-W Set case. Plug the
charging station to a power outlet using the charging
USB-C cable and the USB power adapter.
Up to 8 sensors can be charged simultaneously via
the charging station.
